Metallicity Troubles Secular Cosmologists
People who have been reading this weblog for a spell know that I emphasize definitions, as people can argue with each other about different subjects with the same name. Something that is strange to me is that metals mean something different to astronomers than to the rest of us: Anything heavier than an the atomic weight of helium is a metal.
Now that we know, we can see something amazing. Most stars are overwhelmingly composed of hydrogen and helium. Secular cosmology has a story about the origins of metals that does not work.

Hydrogen is the most abundant element in the universe. It is the lightest element, consisting of one proton encircled by one electron. About 91% of the atoms in the universe are hydrogen. Helium is the next most abundant. It is the second-lightest element, consisting of two protons and two neutrons in the nucleus, encircled by two electrons. Helium constitutes just under 9% of the atoms in the universe. All the remaining elements combined constitute less than 1%. Astronomers refer to these heavier elements as metals. In astronomy, a metal is any element with an atomic number higher than 2. So metals include elements like oxygen, nitrogen, and carbon. Metals pose a serious challenge for advocates of the big bang and secular models of galaxy evolution. But they are a feature and natural expectation of biblical creation.
